Exercise, Regardless of Amount of Sedentary Time, Improves Risk Factors in Kids

Wrong. Training does.

Children and adolescents participating in moderate to vigorous physical activity have a lower cardiometabolic risk profile, including lower HDL-cholesterol levels and systolic blood pressure, regardless of the amount of time they spend sedentary, according to the results of a new study [1]. On the basis of the findings, researchers say that children should be encouraged to increase their participation in physical activity rather than decrease the amount of time they spend sedentary, "as this appears more important in relation to cardiometabolic health."

Clearly a culture of physical fitness, when coupled with proper caloric intake, is important.
